Hm, odd that you mention V0 as an example of deflation because at most gyms I've been to V0 is an example of grade /inflation/. In the Hueco V-scale, V0 is supposed to be equivalent to 5.10 in the Yosemite Decimal System. But not a single gym I've been to sets V0s that are as hard as 5.10. Some gyms introduce a "VB" grade for beginners but their V0 is typically not as hard as the 5.10 they set on ropes. I've always chalked this up (heh) to a need to make an enjoyable "first climb" experience for new climbers (who are typically messing around on boulders to see if they like it before learning to belay). If you start bouldering and can't even do the easiest problem in the gym then it's unlikely you're going to have fun and come back. Unfortunately this leads to disappointing (and in some cases, dangerous!) first outdoor experiences since you try out a V3 and get absolutely shut down because your gym's whole rating system is biased by 1-3 grades.
